We manufacture WIND TURBINE CRANES.

The wind turbine crane we produced can be instead of the large crane hoisting work for wind turbines. This special crane adopts self-climbing type hydraulic hoisting system to replace the past expensive wind turbine maintenance, device--large-scale crawler crane. Its self-climbing hydraulic platform is connected to the tower cantilever harmlessly by multi-touch, which, matched with safety monitoring protecting system, could realize the interlock between the hydraulic and mechanical mechanism. The design of the crane has reached the domestic advanced level successfully. Main features: automatic climbing, electric hydraulic drive, flexible operation, quick maintenance, and reliable performance.

WIND POWER MAINTENANCE CRANE TECHNICIAN

• This kind of special crane adopts guide wheel to climb. The roller is made of wear resistant rubber. Roller rolling along the tower drum surface, and not scratch the tower drum surface. Don't damage the tower drum coating, shape, strength and service life.
• The finite element analysis was carried out on the key structure in the design, precise calculation of the stress and deformation, high strength and low weight of the structure is achieved.
• Claws design adopts hydraulic cylinder movable arm, claws and contact surface design tower drum pressure feedback device, there will be no looseness, slippage, clamping is not tight, and so on and so forth; While paw inside high friction coefficient hard rubber material, not the tower drum including surface coating, shape, strength, service life, such as damage, through the pressure feedback device control hydraulic system, make the claws and tower drum interface won't produce too much stress, would not damage the tower drum or produce plastic deformation.
• Lifting device adopts auto crane jib type, mature technology and reliable.
• Hydraulic system has a complete beforehand alarm, stop working overload. At the same time also has a memory function overload and fault self-diagnosis function.
